In the spring of 2025 I needed a new HVAC company to service my air conditioner and furnace. I wanted to find a company that did not advertise or a chain HVAC company. I signed a maintenance contract with Zilka in May of 2025. I'm so glad I did. Yesterday Jack installed a new whole-house humidifier that is perfect for me. In addition, I had called around for pricing the unit offered and their initial price to me could not be beat. I'm delighted with their service. A big shout out to the knowledgeable ladies that work in the service department and to Nathan in the Parts Department who helped me in this transaction. This company is the real deal when it comes to service. read more

Lalit was amazing! Came out immediately, diagnosed and fixed my problem in minutes for a fair price! Highly recommend!

Great service. They just replaced my 1973 boiler and did a fantastic job. Lalit and his team were excellent. Also, William did a great job designing the new system. I've been using them for over 20 years. read more

I am watching all the other guys TV commercials and thinking, Zilka never lets me down. I had a major electrical problem with a ten year old furnace. Within 24 hours, it was diagnosed, parts ordered and repaired. Everyone was cheerful and professional. World class. read more

Our furnace stopped working and the house temperature was dropping fast with the outside temp at 20f. They came out within 2 hours. The technician was very capable and very professional. I am an engineer and he taught me a lot about the system so I understood everything. Customer service was outstanding. The price they charged was very competitive. I highly recommend Zilka. read more

No BS, straight to the point ... we were last year without AC and I call the usual suspect... and I got an estimated for WOOPing $350 dollars. I call Zilka out of desperation and he actually told me to go and check few thing for him... and pin pointed the capacitor! which was 1/10 of the other guys estimate! and voila... fixed like magic... well professional expertise. Jeremy Forcier was attending me and I think this guy can install an AC unit with his eyes closed. Thank you AC read more

Unprofessional and fraudulent company. Left unfinished work in our home. Never showed up to complete the work, nor answer their emails or telephone calls. Stay away from this company. read more

I cannot say enough good things about Zilka Heating & Cooling. Our furnace went out and they were all over it in no time. Everyone with whom we dealt was courteous and knowledgeable. And their attention to detail is bar none. Highly recommend! read more

I had a new furnace and air conditioner installed by Zilka. I can't say enough for all of the folks at Zilka. Friendly, professional, fair pricing. The people in the office, the salesman, the installers were all great! I highly recommend them. read more

As a contractor myself, it is always great to meet people who are honest and actually know what they are talking about! I have worked with William at Zilka on a number of projects, and he always gives honest, straight forward advice to potential clients even if it means telling them they don't need a new furnace or AC unit! Zilka's level of craftsmanship and attention to detail are excellent. I would not hesitate calling Zilka for your HVAC needs. read more

A few years ago I called Zilka, because the group of blind monkeys who had replaced my furnace 2 years previously could not repair it. The Utility room was very hot, the rest of the house was cold, and the furnace would not shut off until a sensor shut it off due to a dangerous overheating condition. The man who answered the phone diagnosed my problem during the call. The AC evaporator was plugged with dog hair. The hot air could not flow through it. I had my furnaced replaced by Zilka, by my choice, because the furnace had been overheating for over a year a year. I hired Zilka to replace my father in law's furnace last fall. I hired them to replace my AC system. No need to shop around with estimates if you call Zilka. They are highly skilled craftsmen, and do a great job for a fair price. I am calling them this am to repair or replace my father in- law's ac system. read more

First tech they sent out was extremely rude to my wife and I. He completely missed the problem, which caused my basement to flood due to leak in furnace water vent line. They refused to make it right, and insisted on charging me full price for the "service" that took 3 visits, and 3 different techs. The owner, and manager were extremely rude, and basically said that if I didnt like it, "dont call us again." Wow. read more

I moved to the Birmingham in August 2018 and was told by the former owner of the home that I purchased that he had great experience with Zilka Heating & Cooling. Consequently when I wanted to buy a service contract and have some servicing done on my two Heating & Cooling units, I decided to give Zilka a try. A young man has now visited my residence three times named "Lollet" a Service Repair Technician from Zilka. He is undoubtedly one of the best, most knowledgeable and professional service technicians that I have ever used. He was at my home just yesterday to install a part and when talking to him, I made a mental note to get on-line with YELP and let everyone know that he is a first-class, A-1, top-notch repair technician and does a great job in representing his company. If you are looking for an honest and professional Heating & Cooling company, look no further than Zilka for all your needs. You'll be glad you did. read more

William is wonderful to work with! He is so knowledgeable, thorough and makes sure the job is done properly. What fantastic customer service - could not ask for more! read more

I have had great experiences with Zilka and would not call anyone else. When I bought my house in 2005 I needed a new furnace. I got 3 quotes and decided to go with Zilka. They weren't the cheapest quote but my Dad strongly urged me to use Zilka because they had such a good reputation and he thought it was the best value for the money. He was right. William helped us pick out a good furnace and filter system for my needs and they got it installed quickly. The only problem I have had with my furnace was because I was not good about changing the filters. Zilka came out right away when I had a problem and showed me the different filters that need to be changed. 12 years later, my hot water heater just gave out and I didn't bother calling anyone else. Jessica juggled some appointments so she could get Jeremy out to see me within 2 hours. Jeremy was really quick and helpful, and very neat. He was very knowledgeable about different options for the hot water heater. He explained what he was doing and why. He also checked out my furnace and changed the filters for me (I'm still not very good about changing the filters). I couldn't be happier with their service. read more
